Quanta Services (PWR), Houston is quite possibly the country’s biggest builder of electrical infrastructure, and a zillionaire oilman-turned-wind zealot is adding thousands of megawatts of wind power in its backyard.

Investor’s Business Daily has been watching Quanta closely and recently published an interesting article on the company, which through mid-year was working on 30 renewable energy projects, including a solar energy plant that it completed at the Denver International Airport just in time for the Democratic National Convention. The nine-acre system is projected to provide 40 percent of the power supply required to run the airport and save the airport an estimated $13 million over the next 20 years. Quanta provided site preparation and installation services for the more than 9,000 panels required for the system.
